Default tg3 ethernet card drops connection under heavy load

We have an HP DL360 server with dual on-board Tigon3 ethernet cards.
We are using eth0, eth1 is unused at the moment. Sometimes when the
network interface is under heavy load, for example moving large file
transfers over rsync or NFS, the network interface stops working and
we lose all connection to the server. The only solution at this point
is to jump on the console and restart the network interface. I have
not found anything in the log files to indicate what is causing this.
Has anyone else experienced something similar? Or perhaps you know
how I could troubleshoot this?

why don't you start with the kernel version and architecture?
-> uname -a
-> /var/log/messages relevant lines?
-> /sbin/ifconfig -a
-> ethtool eth0 and ethtol eth1

This server is running centos 3.9

There was nothing out of the ordinary in /var/log/messages. The
logging just stops after the network card drops offline. dmesg also
shows nothing out of the ordinary when the driver is loaded. The
network card works fine until it is under heavy load.

Upgrade the driver? Back in my RHEL3 days(I noticed you
were running CentOS 3.9), we didn't even bother using the broadcom
NICs and instead installed e1000 on all the systems due to driver
issues with the broadcom chips(this was back in 2003-2005, DL360G2-G3).

Get the latest drivers at www.broadcom.com

Since you are running CentOS 3 I am assuming this server has been in
production for some time. Did these symptoms just start?
Did you do any updates before this started happening?
Did you install this equipment, or did you assume admin duties from someone
else? Maybe it had the HP net driver installed, and a kernel update broke that.

It appears to be a faulty NIC card. We moved the connection over to
the other card and have not had any problems since. Sometimes it's
just plain "broken"!
